Authorities are actively searching for the Brown University gunman who killed two students and injured nine others, utilizing video evidence and a $50,000 reward for tips. New footage shows the suspect in a mask and dark jacket, approximately 5 feet 8 inches tall, prompting public assistance for identification. Police have resumed their investigation after releasing a previous person of interest, as they sift through snow and dumpsters for further evidence. The shooting caused chaos during final exams, and officials are enhancing security measures at local schools.
